The present application discloses an energy-saving air conditioner and its control method. The energy-saving air conditioner includes: a controller, a compressor refrigeration cycle and a natural cold source cycle. The controller controls the compressor refrigeration cycle and the natural cold source cycle to operate independently, or the controller controls the compression The mechanical refrigeration cycle and the natural cold source circulation are connected into one cycle; the compressor refrigeration cycle includes: the first indoor heat exchanger, the seventh solenoid valve, the compressor, the first one-way valve, the first outdoor heat exchanger, The first solenoid valve and expansion valve; the natural cold source cycle includes: the second indoor heat exchanger, the second one-way valve, the second outdoor heat exchanger, the second solenoid valve and the circulating pump connected in sequence; the first indoor heat exchanger The heat exchanger and the second indoor heat exchanger use the same indoor fan; the first outdoor heat exchanger uses the first outdoor fan, and the second outdoor heat exchanger uses the second outdoor fan. This energy-efficient air conditioner operates in different modes according to needs, which helps to improve the energy efficiency of the air conditioner.
Description
technical field [0001] The present application relates to the technical field of air conditioners, in particular to an energy-saving air conditioner and a control method thereof. Background technique [0002] As the number and size of communication rooms and data centers continue to expand, the power consumption of computer room air conditioning systems used to cool electronic equipment is also increasing. With the continuous advancement of energy conservation and emission reduction policies, and the society's attention and control on the energy efficiency of communication equipment rooms and data centers, equipment room air conditioners are facing higher energy-saving requirements. [0003] The energy-saving air conditioners currently in use cannot fully use the outdoor natural cold source for cooling, and cannot fully meet the needs of energy saving in the computer room, dynamic cooling according to indoor and outdoor temperature changes, and automatic optimization of ener...
